Anterior cervical bone protrusion generally refers to a more prominent bone in the front of the neck. Anterior cervical bone protrusion may be caused by physiological reasons such as bony standards, long and thin body type, or it may be caused by scoliosis, tension of the sternocleidomastoid muscle, thyroid disease and other pathological reasons. 1. Physiological reasons: normal people’s anterior neck is generally thyroid cartilage, cricoid cartilage and other bony standards, belonging to the body’s normal structure, play the role of bony positioning, itself will appear a more obvious bony prominence; secondly, the thin and long body type people, the neck of the adipose tissue is more less, these bony prominence will be more obvious. 2. Pathological reasons: patients with lesions in the anterior neck tissues or spinal deformities may also have bony protrusions in the anterior neck. Such as scoliosis deformity, tension and spasm of sternocleidomastoid muscle caused by various reasons, calcification of thyroid gland and other diseases, pathological causes may lead to asymmetry or direct ossification of anterior cervical tissues, and there may be a situation where the bone is more protruding. There may be other reasons for the protrusion of the anterior cervical bone, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
